It swaps the factory head bolts for studs, nuts and washers. The studs are wound into the block by hand and the head is clamped by torquing the nuts, which gives more even, repeatable clamping than factory stretch bolts and saves wear on the block threads each time the head comes off.\u003c\/p\u003e\n\u003cp\u003eMore clamping load helps the head gasket seal against high cylinder pressure, which is why head studs are one of the first parts fitted to a boosted or high-compression build.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBefore you order:\u003c\/strong\u003e 16-valve 4A-GE only (not the 20-valve).\u003c\/p\u003e\n\u003cp\u003eSee the Vehicle Fitment tab for the full list of vehicles.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Installation by a professional is recommended.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMade in the USA by ARP\u003c\/li\u003e\n\u003cli\u003eThread \/ diameter: M10 x 1.25\u003c\/li\u003e\n\u003cli\u003eARP torque spec: 60 ft-lb (81 Nm) in three steps with ARP Ultra-Torque\u003c\/li\u003e\n\u003cli\u003eInstallation instructions available from ARP (see Technical Specifications)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"chicane-links\"\u003eShop more: \u003ca href=\"\/collections\/arp\"\u003eARP\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eNeed help choosing parts?
